While I do not have a pair of their breathable light weights, we have had excellent results with Bare waders. Cost less than Simms and are another option. Your making a good call to spend some money on quality waders. Can't tell you how many times I have fished with people who have a 700 dollar pole and 49 dollar waders. I feel that if you spend much time fishing the rivers, your wading gear is more importaint than your rod.. its hard to fish if your wet and cold.. no matter what kind of rod you have.
